Ruan Yongbin
Ruan Yongbin ( Chinese 阮勇斌 , Pinyin Ruǎn Yǒngbīn ; born February 14, 1963 ) is a Chinese mathematician who studies algebraic geometry, differential geometry and symplectic geometry with applications in string theory .
Ruan studied from 1978 at the Sichuan University with the diploma degree in 1985. 1985/86 he was teaching assistant at the University of Wisconsin . He received his PhD in 1991 under Robion Kirby (and Tomasz Mrowka ) at the University of California, Berkeley ( Gauge theory and its applications to Riemannian Geometry ). He was a post-graduate student at Michigan State University . In 1993 he became an Assistant Professor at the University of Utah , in 1995 Associate Professor and in 1999 Professor at the University of Wisconsin – Madison . Since 2006 he has been a professor at the University of Michigan .
Among other things, he was visiting professor at ETH Zurich , in Hong Kong and at MIT. In 1993 and 2004 he was at IHES , in 1993 at the Max Planck Institute for Mathematics , in 1994 at the Isaac Newton Institute and in 1994 at the MSRI .
In 1998 he was invited speaker at the International Congress of Mathematicians in Berlin ( Quantum Cohomology and its Applications ). From 1995 to 1997 he was a Sloan Research Fellow . He is a fellow of the American Mathematical Society .
